Why it works: Pepper and clove match in chemistry and in kitchens. They rank in the top 5% of all ingredient pairs, and cooks put them together in 17,451 recipes. Both carry ethyl octanoate, which smells fruity, wine. The science ↓
French Beans
Ingredients
Directions
Brine the beans
Make a strong brine by dissolving the salt in water.
Gather the beans before they have strings and lay them in the brine until they turn yellow.
Pickle
Drain the beans and pour boiling hot vinegar over them.
Seal the container tightly and let it sit for one day and night.
Boil the vinegar and pour it over the beans again for several days until they turn green.
Spice
Add the pepper, mace, and cloves to the beans.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Green beans
- The main vegetable, which softens in the brine and vinegar and takes on the pickled flavor and color.
- Coarse sea salt
- Draws water out of the beans in the brine, firming their texture and seasoning them.
- Vinegar
- Its acidity preserves the beans and gives the pickle its sharp, tangy flavor.
- Black pepper
- Adds sharp, warm aroma and flavor to the pickled beans.
- Mace
- Adds a warm, aromatic spice flavor to the pickle.
- Cloves
- Adds a strong, warm aroma to the pickle.
The step that matters
Pour boiling hot vinegar over the beans. Hot vinegar penetrates the beans more readily and its acidity helps preserve them. The beans must stay fully covered by the liquid, since any exposed part can spoil or discolor.
Swap the green beans
How well each one fits the dish's main ingredients (vinegar, pepper, mace, clove):
- Capsicumfits better
- Carrotfits better
- Mustardfits better
- Green beansthe original
Fit is the average pairing score against vinegar, pepper, mace, clove. Candidates are from the same food group and used in at least 100 recipes.
